Alp Toker 0621cb2e7d Make clang's rewrite engine a core feature
The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.

Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.

Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

Anna Zaks b8de0c4278 Do not inline methods of C++ containers (coming from headers).
This silences false positives (leaks, use of uninitialized value) in simple
code that uses containers such as std::vector and std::list. The analyzer
cannot reason about the internal invariances of those data structures which
leads to false positives. Until we come up with a better solution to that
problem, let's just not inline the methods of the containers and allow objects
to escape whenever such methods are called.

This just extends an already existing flag "c++-container-inlining" and applies
the heuristic not only to constructors and destructors of the containers, but
to all of their methods.

Manuel Klimek 264f963114 Fix crash when resolving branch conditions for temporary destructor condition blocks.
Document and simplify ResolveCondition.

1. Introduce a temporary special case for temporary desctructors when resolving
the branch condition - in an upcoming patch, alexmc will change temporary
destructor conditions to not run through this logic, in which case we can remove
this (marked as FIXME); this currently fixes a crash.

2. Simplify ResolveCondition; while documenting the function, I noticed that it
always returns the last statement - either that statement is the condition
itself (in which case the condition was returned anyway), or the rightmost
leaf is returned; for correctness, the rightmost leaf must be evaluated anyway
(which the CFG does in the last statement), thus we can just return the last
statement in that case, too. Added an assert to verify the invariant.

Jordan Rose 62ac9ecadc [analyzer] Don't assert when combining using .* on a temporary.
While we don't model pointer-to-member operators yet (neither .* nor ->*),
CallAndMessageChecker still checks to make sure the 'this' object is not
null or undefined first. However, it also expects that the object should
always have a valid MemRegion, something that's generally important elsewhere
in the analyzer as well. Ensure this is true ahead of time, just like we do
for member access.

NAKAMURA Takumi 7da9487dd4 [CMake] Get rid of explicit dependencies to include/clang/*.inc and introduce CLANG_TABLEGEN_TARGETS.
This does;
  - clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
  - List of targets is added to LLVM_COMMON_DEPENDS.
  - all clang libraries and targets depend on generated headers.

You might wonder this would be regression, but in fact, this is little loss.
  - Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
  - clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
  - Each library's dependencies to tblgen'd files might vary along headers' structure.
    It made hard to track and update *really optimal* dependencies.

Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

Summary:
In clang-tidy we'd like to know the name of the checker producing each
diagnostic message. PathDiagnostic has BugType and Category fields, which are
both arbitrary human-readable strings, but we need to know the exact name of the
checker in the form that can be used in the CheckersControlList option to
enable/disable the specific checker.

This patch adds the CheckName field to the CheckerBase class, and sets it in
the CheckerManager::registerChecker() method, which gets them from the
CheckerRegistry.

Checkers that implement multiple checks have to store the names of each check
in the respective registerXXXChecker method.

A return type is the declared or deduced part of the function type specified in
the declaration.

A result type is the (potentially adjusted) type of the value of an expression
that calls the function.

Rule of thumb:

  * Declarations have return types and parameters.
  * Expressions have result types and arguments.

Jordan Rose 2a833ca575 [analyzer] BlockCall shouldn't really be an AnyFunctionCall.
Per discussion with Anna a /long/ time ago, it was way too easy to misuse
BlockCall: because it inherited from AnyFunctionCall (through SimpleCall),
getDecl() was constrained to return a FunctionDecl, and you had to call
getBlockDecl() instead. This goes against the whole point of CallEvent
(to abstract over different ways to invoke bodies of code).

Now, BlockCall just inherits directly from CallEvent. There's a bit of
duplication in getting things out of the origin expression (which is still
known to be a CallExpr), but nothing significant.

Jordan Rose c9176072e6 [analyzer] Add a CFG node for the allocator call in a C++ 'new' expression.
In an expression like "new (a, b) Foo(x, y)", two things happen:
- Memory is allocated by calling a function named 'operator new'.
- The memory is initialized using the constructor for 'Foo'.

Currently the analyzer only models the second event, though it has special
cases for both the default and placement forms of operator new. This patch
is the first step towards properly modeling both events: it changes the CFG
so that the above expression now generates the following elements.

1. a
2. b
3. (CFGNewAllocator)
4. x
5. y
6. Foo::Foo

The analyzer currently ignores the CFGNewAllocator element, but the next
step is to treat that as a call like any other.

The CFGNewAllocator element is not added to the CFG for analysis-based
warnings, since none of them take advantage of it yet.

Jordan Rose 1a866cd54b [analyzer] Model getters of known-@synthesized Objective-C properties.
...by synthesizing their body to be "return self->_prop;", with an extra
nudge to RetainCountChecker to still treat the value as +0 if we have no
other information.

This doesn't handle weak properties, but that's mostly correct anyway,
since they can go to nil at any time. This also doesn't apply to properties
whose implementations we can't see, since they may not be backed by an
ivar at all. And finally, this doesn't handle properties of C++ class type,
because we can't invoke the copy constructor. (Sema has actually done this
work already, but the AST it synthesizes is one the analyzer doesn't quite
handle -- it has an rvalue DeclRefExpr.)

Modeling setters is likely to be more difficult (since it requires
handling strong/copy), but not impossible.

Jordan Rose 656fdd55dd [analyzer] Warn about double-delete in C++ at the second delete...
...rather somewhere in the destructor when we try to access something and
realize the object has already been deleted. This is necessary because
the destructor is processed before the 'delete' itself.

a better one.)

Chandler Carruth 5553d0d4ca Sort all the #include lines with LLVM's utils/sort_includes.py which
encodes the canonical rules for LLVM's style. I noticed this had drifted
quite a bit when cleaning up LLVM, so wanted to clean up Clang as well.

Alp Toker ef6b007dc5 Only mark dump() function definitions 'used' in debug builds
This has the dual effect of (1) enabling more dead-stripping in release builds
and (2) ensuring that debug helper functions aren't stripped away in debug
builds, as they're intended to be called from the debugger.

Note that the attribute is applied to definitions rather than declarations in
headers going forward because it's now conditional on NDEBUG:

  /// \brief Mark debug helper function definitions like dump() that should not be
  /// stripped from debug builds.

Requires corresponding macro added in LLVM r198456.

Alp Toker 95e7ff2ed1 Eliminate UnaryTypeTraitExpr
Remove UnaryTypeTraitExpr and switch all remaining type trait related handling
over to TypeTraitExpr.

The UTT/BTT/TT enum prefix and evaluation code is retained pending further
cleanup.

This is part of the ongoing work to unify type traits following the removal of
BinaryTypeTraitExpr in r197273.

Alp Toker cbb9034e2a Eliminate BinaryTypeTraitExpr
There's nothing special about type traits accepting two arguments.

This commit eliminates BinaryTypeTraitExpr and switches all related handling
over to TypeTraitExpr.

Also fixes a CodeGen failure with variadic type traits appearing in a
non-constant expression.

The BTT/TT prefix and evaluation code is retained as-is for now but will soon
be further cleaned up.

This is part of the ongoing work to unify type traits.

and code to produce address space casts from those kinds when appropriate.
